Abstract

A mobile device implemented method includes receiving a request at the mobile device from a user to make an emergency call over a network, attempting to place the emergency call via the mobile device,detecting a failure of random access attempt procedure for the emergency call by the mobile device, using a reduced back off parameter value as compared to a back off parameter value for a non-emergency call, and re-attempting the random access procedure for the emergency call via the mobile device as a function of the reduced back off parameter value.

Description

[0001] Related Applications Cross Application [0002] This application claims priority to an earlier application, U.S. Nonprovisional Patent Application No. 15 / 006,896, filed January 26, 2016, entitled "Emergency Call Priority," the contents of which are incorporated by reference and into this article. technical field [0003] The present application relates to a contention-based random access procedure for setting up a call, and particularly relates to prioritizing an emergency call in the contention-based random access procedure to reduce time delay when a conflict occurs. Background technique [0004] When trying to initiate a call, the mobile phone first initiates a random access procedure. If the access attempt fails, the mobile phone will wait for the random backoff time to expire according to the uniform distribution between 0 and the backoff parameter value before starting the random access procedure. When multiple devices compete for network resources at the same...
